Simulation & modelling of a wind turbine using PMSG with maximum power tracking control

The performance research and analysis of a wind power system driven by a low speed Permanent Magnet Synchronous Generator (PMSG) in MATLAB/Simulink simulation software is discussed in this work. The system includes of a wind turbine (WT), a power management system (PMSG), maximum power point tracking (MPPT), a three-phase diode bridge rectifier, a dc bus connected to a capacitor, and a PWM voltage source inverter regulated by a current source. The best coefficient of performance parameter in the WT model was obtained as a function of wind velocity using an MPPT control. Because of the usage of low speed PMSG, which results in improved efficiency, the gearbox is not necessary. The use of low-speed PMSG, which results in improved efficiency, eliminates the need for a gearbox. The ac output power obtained from PMSG is supplied to a three-phase rectifier bridge, which allows for maximum power extraction by using the boost converter's optimal voltage and current settings. The total system is connected to the electrical utility using a current source PWM inverter for dc/ac conversion.
